Chapter 1: Introduction Chapter 1: Introduction 1.1 Satellite Differential System The Raystar 120 Satellite Differential GPS Receiver utilizes a new satellite differential system to improve the accuracy, integrity and availability of the basic GPS signals, resulting in satellite differential corrections and enhanced positional accuracy over standard GPS receivers.
Geostationary Satellites which broadcast the corrected data on the standard GPS frequency, making it available to the user’s Raystar 120 GPS Receiver. The Raystar 120 GPS Receiver uses the correctional data transmitted by the Geostationary Satellites to refine the GPS positional data for greater accuracy.
EGNOS is currently in the early testing and qualification phases and signal outages may occur at any time. The status of EGNOS and any planned outages are available on-line at Raymarine’s website: http://www.raymarine.com Use of Satellite Differential is currently disabled outside of the WAAS reception area.
The navigational accuracy of equipment using these satellite broadcast SD signals during the testing and qualification phases is not guaranteed by Raymarine Limited, nor is the continuation of the broadcast SD signals the responsibility of Raymarine Limited or Raytheon Corporation.
Raymarine equipment should be serviced only by authorized Raymarine service technicians. They will ensure that service pro- cedures and replacement parts used will not affect performance. There are no user serviceable parts in this Raymarine product. • When powered up, all electrical equipment produces electromag- netic fields.

NMEA Version The unit is normally connected to an NMEA system via a 33ft (10m) cable terminated with a moulded 6-pin connector.
Figure 2-3 to Figure 2-3 below. Note: As with all onboard marine equipment, the installer should en- sure that the power supply connection to the Raystar 120 is adequate- ly protected by a suitably rated fuse or circuit breaker. This will be provided, typically, by connection via a fused display unit.
